The demo highlighted key UE5.6 features including Nanite Foliage for dense vegetation, Fast Geometry Streaming for improved world loading, and realistic character animation with muscle simulation. Running at 60 FPS with ray tracing on PlayStation 5, the demo rendered over 300 skeletal mesh agents without performance impact, demonstrating the engine's capabilities for open-world gaming ahead of the game's 2027 release. ## Content # The Witcher 4's Unreal Engine 5.6 Tech Demo Unveiled at State of Unreal 2025 At the State of Unreal 2025 event, CD Projekt Red unveiled a tech demo of The Witcher 4, detailing potent advancements in game development through Unreal Engine 5.6. While the footage showcased was purely a technological demonstration, it offered a glimpse into the promising capabilities in store for the upcoming game. ### Unreal Engine 5.6 Enhancements The demo displayed remarkable improvements inherent in Unreal Engine 5.6, particularly tailored for open-world game development. Key features included: - **Nanite Foliage for Dense Vegetation:** This feature allows dense vegetation rendering, crucial for crafting immersive open-world environments. - **Fast Geometry Streaming Plugin:** Facilitates expedited world loading, enhancing the overall gameplay experience. - **Realistic Character Animation:** Includes muscle simulation for lifelike character movements, marking a cutting-edge advancement in animation fidelity. ### Showcasing Ciri in Kovir In the tech demo, Ciri, the new protagonist, traverses the region of Kovir, exemplifying improved environmental details that bring the world closer to reality. The demo ran seamlessly at 60 FPS with ray tracing enabled on the base PlayStation 5, underscoring the efficiency of Unreal Engine 5.6 in handling complex graphical processes. ### Demonstrating Gaming Efficacy A standout feature of the demonstration was its ability to render over 300 skeletal mesh agents in a single scene without impacting performance, showcasing UE5.6's robust handling of high-density animations and scenes. This demonstration indicates the game's potential once released, though the final gameplay might differ from this tech demo. ### Future Developments CD Projekt Red is at the brink of delivering its most advanced project yet, scheduled for launch in 2027. Collaborating with Epic Games since 2022, this move signifies an era where open-world gaming is set to reach new heights. As CD Projekt Red continues to develop multiple Witcher projects in parallel with a sequel to Cyberpunk 2077, the anticipation for The Witcher 4 rises. While the game itself remains in development, the technology showcased in the demo promises an exciting future ahead. ## Community discussion Top comments from developers on daily.dev. **@capjavert** · 0 upvotes > Awesome stuff! ## Similar posts on daily.dev - [Don’t just attend KubeCon \+ CloudNativeCon, Merge Forward your experience\!](https://daily.dev/posts/don-t-just-attend-kubecon-cloudnativecon-merge-forward-your-experience--l0rpp73x8) · CNCF · 1 upvotes · 0 comments - [Announcing H2 2026 KCDs](https://daily.dev/posts/announcing-h2-2026-kcds-m96goajm1) · CNCF · 1 upvotes · 0 comments - [Two months of Open Community Groups](https://daily.dev/posts/two-months-of-open-community-groups-asf52zhbs) · CNCF · 0 upvotes · 0 comments - [CNCF Unveils Schedule for KubeCon \+ CloudNativeCon Europe 2026](https://daily.dev/posts/cncf-unveils-schedule-for-kubecon-cloudnativecon-europe-2026-ikhcoa5cb) · CNCF · 2 upvotes · 0 comments - [CNCF Debuts KubeCon \+ CloudNativeCon Japan 2026 Schedule](https://daily.dev/posts/cncf-debuts-kubecon-cloudnativecon-japan-2026-schedule-xp5pyudub) · CNCF · 1 upvotes · 0 comments --- Tags: [#performance](https://daily.dev/tags/performance), [#game-development](https://daily.dev/tags/game-development), [#3d](https://daily.dev/tags/3d), [#unreal-engine](https://daily.dev/tags/unreal-engine) [View this post on daily.dev](https://daily.dev/posts/exploring-the-witcher-4-innovations-in-unreal-engine-5-6-dgb5bckkf) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Exploring The Witcher 4: Innovations in Unreal Engine 5.6","url":"https://daily.dev/posts/exploring-the-witcher-4-innovations-in-unreal-engine-5-6-dgb5bckkf","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/exploring-the-witcher-4-innovations-in-unreal-engine-5-6-dgb5bckkf"},"datePublished":"2025-06-03T14:27:54.812Z","dateModified":"2025-06-04T13:02:18.984Z","description":"CD Projekt Red showcased The Witcher 4 tech demo using Unreal Engine 5.6 at State of Unreal 2025.
